Hi WGLowe,
Here's the quick answer:
Your email is showing up in the junk / spam folders because the server that is receiving your email thinks it is spam.
Here's the problem:
As it is the receiver's email server labeling your email as spam, there's nothing directly you can do to stop this.
There is hope!
Setting up SPF Records and Domain Keys is a good way to help prevent this.
I wish we were able to fix this for you, but unfortunately we can only control our servers, and have no pull in how other mail servers filter / label spam. Take a look at the link I posted about about SPF Records and Domain keys though, and let us know if you have any questions.
Thanks,
- Brad
